On Friday, May 10, 2013, the 150th anniversary of Jackson's death, a trauma surgeon with experience on the battlefield in Iraq and Afghanistan has reinvestigated the medical record to offer a diagnosis of Jackson's death. University of Maryland surgeon Joseph DuBose says Jackson likely died of pneumonia. He is confirming the diagnosis given by Jackson's physician, the famed Confederate doctor Hunter McGuire.
